The e-SRN/E cable siren-announcement device, which controls siren sounds, announcements, and the light warning system for emergency vehicles such as police, ambulances, and fire services, is an innovative siren system designed to integrate multiple functions into a single unit. The keypad on the control panel controls the broadcast of announcements and the control of audible and visual warnings. A sunlight-readable color TFT screen simulates the flashing mode of the light warning system, and errors in the beacon are visually displayed. The control panel menu, which displays statuses such as the siren type, day/night mode, and volume level, allows you to configure numerous functions and select parameters for certain functions. Siren sounds can also be downloaded to the device via a separate configuration program; the device can broadcast siren frequencies specific to the country or sector in which it will operate. The e-SRN/E siren's screen visually simulates multiple operating functions, and the user is informed of errors, indicating the type and location of the error. Audio from an external source (radio, radio station, recording device, etc.) is transmitted to the system via the AUX input and can be broadcast to the outside world via an external speaker. Furthermore, the push-to-talk button and microphone on the remote control allow for high-quality audio broadcasts, with adjustable volume levels.
